Mostly True

Fifteen minutes of shivering can be metabolically equivalent to one hour of exercise.

Infact verdict: Mostly True (62/100).

The claim that fifteen minutes of shivering can be the metabolic equivalent of one hour of exercise is supported by evidence from a study mentioned in National Geographic. The study suggests that shivering increases metabolism and fat oxidation, potentially equating to the calorie burn of an hour of exercise. However, the evidence is primarily based on a single study, and while it is reported by a medium-reliability source, further corroboration from additional high-quality sources would strengthen the claim. Therefore, the claim is plausible but requires more evidence for higher confidence.
